The next Great Prophecy is in progress, and the seven demigods were making their way to Greece, the roots of all the gods. There has been a huge setback, now that the two main leaders have fallen into the depths of the Underworld, Tartarus. Everyone feels responsible, everyone blames themselves, and that isn't helping at all. Now the remaining demigods must keep the promise that Nico Di Angelo made, and make their way to Epirus, Greece.
However, there is another major setback. Gaea, throws crazy and nearly impossible challenges at all of the demigods, all of them nearly facing death more than a couple of times. In the end, Gaea is more powerful, has a very large army, and her twelve sons, the giants. Against all the odds, will the seven demigods be able to defeat Gaea and once again, save the world?
